嵌入式Undertown同时部署websocket和servlet，不起作用

Question

我是使用 undertow 的新手，我正在开发一个独立的应用程序，将其用作嵌入式服务器。我希望我可以在我的嵌入式 undertow 中部署 web sockets、servlet 和 restfull htmls 服务。

到目前为止，我只使用 web 套接字和 servlet 完成了测试，每个单独的功能都正确的问题，但是如果我删除 servlet 页面，我不会从带有 HTML 和 JavaScript 的测试页面访问的 web 套接字部署它们nigun 测试运行没有错误。

这是我的代码：

    /*
     * Create the  appWebSocketDeploymentInfo and configure
     */
    WebSocketDeploymentInfo appWebSocketDeploymentInfo = new WebSocketDeploymentInfo();
    appWebSocketDeploymentInfo.setBuffers(new ByteBufferSlicePool(BufferAllocator.BYTE_BUFFER_ALLOCATOR, 17000, 17000 * 16));
    appWebSocketDeploymentInfo.addEndpoint(WebSocketEndpoint1.class);
    appWebSocketDeploymentInfo.addEndpoint(WebSocketEndpoint2.class);

    /*
     * Create the  appDeploymentInfo and configure
     */
    DeploymentInfo appDeploymentInfo = Servlets.deployment()
                                    .setClassLoader(Server.class.getClassLoader())
                                    .setContextPath("/myapp)
                                    .setDeploymentName("app.war")
                                    .setResourceManager(new FileResourceManager(new File("src/main/webapp"), 1024))
                                    .addServlets(Servlets.servlet("HomeServlet", HomeServlet.class).addMapping("/home"))
                                    .setResourceManager(new ClassPathResourceManager(Server.class.getClassLoader(), Server.class.getPackage()))
                                    .addServletContextAttribute(WebSocketDeploymentInfo.ATTRIBUTE_NAME, appWebSocketDeploymentInfo);

    /*
     * Create the deploymentManager
     */
    deploymentManager = Servlets.defaultContainer().addDeployment(appDeploymentInfo);

    /*
     * Deploy the app
     */
    deploymentManager.deploy();

    /*
     * Create the path handle
     */
    pathHandler = Handlers.path(Handlers.redirect("/myapp/home")).addPrefixPath("/myapp", deploymentManager.start());

    /*
     * Create the server
     */
    undertowServer = Undertow.builder().addHttpListener(DEFAULT_PORT, DEFAULT_IP).setHandler(pathHandler).build();

javascript日志错误是

WebSocket 连接到“ws://localhost:8080/fermat/node-channel”失败：WebSocket 握手期间出错：意外响应代码：404

经过广泛的测试和研究，我得到了正确的配置和启动服务器的方法，还将添加对其他技术的支持，例如：

• WebSocket
• 放心
• 焊接

我的最终代码：

UndertowJaxrsServer server = new UndertowJaxrsServer();
Undertow.Builder serverBuilder = Undertow.builder().addHttpListener(DEFAULT_PORT, DEFAULT_IP);
ServletContainer servletContainer = Servlets.defaultContainer();

   /*
    * Create the App WebSocketDeploymentInfo and configure
    */
    WebSocketDeploymentInfo appWebSocketDeploymentInfo = new WebSocketDeploymentInfo();
    appWebSocketDeploymentInfo.setBuffers(new    ByteBufferSlicePool(BufferAllocator.BYTE_BUFFER_ALLOCATOR, 17000, 17000 * 16));
    appWebSocketDeploymentInfo.addEndpoint(WebSocketNodeChannelServerEndpoint.class);
    appWebSocketDeploymentInfo.addEndpoint(WebSocketClientChannelServerEndpoint.class);

    /*
     * Create the App ResteasyDeployment and configure
     */
    ResteasyDeployment deployment = new ResteasyDeployment();
    deployment.setApplicationClass(JaxRsActivator.class.getName());
    deployment.setInjectorFactoryClass("org.jboss.resteasy.cdi.CdiInjectorFactory");

    /*
     * Create the App DeploymentInfo and configure
     */
    DeploymentInfo appDeploymentInfo  = server.undertowDeployment(deployment, APP_NAME);
    appDeploymentInfo.setClassLoader(FermatEmbeddedNodeServer.class.getClassLoader())
                    .setContextPath(APP_NAME)
                    .setDeploymentName(WAR_APP_NAME)
                    .addServletContextAttribute(WebSocketDeploymentInfo.ATTRIBUTE_NAME, appWebSocketDeploymentInfo)
                    .addServlets(Servlets.servlet("HomeServlet", HomeServlet.class).addMapping("/home"))
                    .addListeners(Servlets.listener(org.jboss.weld.environment.servlet.Listener.class));

    server.deploy(appDeploymentInfo);
    server.start(serverBuilder);
